Playing Mass Effect 2 for the first time, I had the same feeling of 'they aren't telling me how to play the game!'. Sure, there was some help, but other things just never got mentioned and I had to either stumble on it, or ask my brothers.

On the one hand, it's rather satisfying to find or solve things for myself.

On the other hand, it's incredibly frustrating to be most of the way through the game and discover I have been doing things the hard way....
